Vortech Superchargers Tuner Kit - V-2 Si - 10-Rib - Satin (Carbureted Small Block Chevrolet) 4GP218-040SQ
Satin V-2 Si 10-Rib Tuner Supercharger Kit for Carbureted Small Block Chevy
The Vortech Superchargers Tuner Kit (PN 4GP218-040SQ) is a revised, universal supercharging solution engineered for carbureted Small Block Chevrolet engines where flexibility and custom configuration are the priority. Featuring the V-2 Si centrifugal supercharger in a durable satin finish, this tuner kit is designed for builders running aftermarket EFI systems or alternate carburetor hats, bonnets, or enclosure boxes.
Unlike complete systems, this tuner kit does not include a carburetor enclosure box, giving experienced builders and tuners the freedom to select their preferred induction and fuel strategy. Developed through extensive testing in Vortech's supercharger lab, the V-2 Si delivers exceptional efficiency and reliability for street, strip, and competition-focused carbureted SBC builds.
V-2 Si Supercharger Technology
The V-2 Si utilizes a helical gear-driven centrifugal design optimized for smooth operation and long-term durability. With a peak 78% adiabatic efficiency (SAE J1723), the Si-Trim compressor produces cooler discharge temperatures, reduced parasitic load, and increased net horsepower compared to traditional forced-induction designs.
Performance Potential
- Horsepower Gains: Approximately 30% to more than 75% (application dependent)
- Typical Boost: ~8-10 PSI at 5,500 RPM on a mildly modified 350ci engine
- Maximum Power Capability: Up to ~775 HP with proper supporting modifications
Tuner Kit Configuration
This tuner kit configuration is intended for custom builds and does not include Vortech's carburetor enclosure box. Builders may run:
- Aftermarket EFI systems
- Alternate carburetor hats or bonnets
- Optional Vortech Maxflow Carburetor Enclosure Box (sold separately)
For customers seeking a complete bolt-on solution, Vortech also offers complete systems that include the Maxflow carburetor enclosure assembly.
